Introduction: Laser Music Visualizer
You know how your favorite songs sound like. Now you can make a visualizer and see how they look like.
It works like this: When you play sound through your speaker, the diaphragm of the speaker vibrates. These vibrations move the mirror attached to the speaker up and down which in turn affects how the laser light is reflected from the mirror.
A small decorative mirror
Some tape (or glue)
Step 1: Gather the Supplies
Step 2: Attach Mirror to Speaker's Diaphragm
Step 3: Place Speaker at Some Height
Step 4: Position the Laser
Position the laser such that it bounces light off the speaker and onto the wall
Step 5: Turn Off the Lights and Play Music
Turn the lights off and play your favorite songs through the speaker. Enjoy the amazing light show!
As a bonus, try playing sounds of varying frequencies and notice the pattern.
Did you notice something interesting? ;-)
